Hello Negativ1337,

Robash is correct.

1. You don't need Synergy, this is only usefull when you want to use more than one pc.

2. Autohotkeys will do just fine.

All it does ist sending your keystrokes in client one to client two.

There are many tutorials here in the forum on how to set it up.

3. I have a similar computer with just 1gig of ram.

I can run 2 instances of wow with ~20-25 Frames on it.

You should get more than that.

4. As a start you should get Autohotkey and think about your key layout. and interface.

My tip is to make good use of the alt key. That should work fine with two chars.

Two mages should be very easy. Just put (for a frostmage) Frostbold on 1 for both and both will start to cast it when you press 1.
